Cellulose oxidation by a perfluorinated hydrocarbon solution of nitrogen dioxide. |
摘要 |
<p>A process for oxidizing cellulose involves reacting the cellulose with a solution of nitrogen dioxide in a perfluorocarbon solvent. In preferred embodiments, the solvent has a boiling point in the range between about 30 DEG C and 100 DEG C, the nitrogen dioxide concentration in the solution is in the range between about 2% and 12% by weight, and the reactants are maintained at a temperature between about 25 DEG C and 60 DEG C during a reaction time of at least about 7 hours.</p> |
